SINKO KOGYO has announced a plan to increase its production of air conditioning units for data centers by 60% by fiscal year 2032.
At first glance, this might seem counterintuitive. With AI servers like NVIDIA's GB200 becoming incredibly powerful and hot, the industry is rapidly shifting towards Direct Liquid Cooling (DLC). So, why would a company double down on traditional air conditioning? The answer lies in the reality of the 'hybrid cooling' era, where both systems coexist and are essential.
Here’s how it works. First, DLC is indeed becoming the primary solution for cooling high-density server racks, directly tackling the intense heat generated by AI chips. However, it doesn't eliminate the need for room-level air conditioning. Industry experts, including Uptime Institute and vendors like Vertiv, agree that air conditioning will continue to manage a significant portion—roughly 20%—of the total heat load in a facility. Its roles include managing ambient temperature and humidity, cooling less-dense IT equipment, handling ventilation, and providing a critical safety margin during maintenance or DLC system failures.
Second, the timing of SINKO's decision is driven by overwhelming market signals. In late April 2026, major hyperscalers announced staggering increases in their capital expenditure (CapEx). Meta, Alphabet (Google), and Microsoft all signaled plans to pour tens of billions more into their AI infrastructure. This massive wave of investment creates a powerful ripple effect across the entire supply chain, boosting demand for everything from power systems to cooling equipment. SINKO is positioning itself to capture this guaranteed slice of the pie.
Finally, there are factors specific to the Japanese market. With major data center hub projects underway (like the one in Toyama) and government policies encouraging energy efficiency, there's a growing advantage for domestic suppliers. SINKO's local manufacturing and advanced testing facilities give it a competitive edge in delivery times and reliability, making it a prime candidate for these new projects. SINKO's move is a calculated bet not against liquid cooling, but on the enduring and essential role of air conditioning as a partner technology.
- Direct Liquid Cooling (DLC): A method where liquid coolant is brought into direct or close contact with hot components like CPUs and GPUs to dissipate heat more efficiently than air.
- Hyperscaler: A large-scale cloud service provider that operates massive data centers, such as Amazon (AWS), Google (GCP), and Microsoft (Azure).
- CapEx (Capital Expenditure): Funds used by a company to acquire, upgrade, and maintain physical assets such as property, buildings, and equipment.
